' My invention relates "to" chick brooders, 'more particularly .tothat class of chick brooders having a canopy positioned above a burner or heater to diffuse the heat.

Ithas been customary in the'ipast to-provide 'a brooder of. the class describedwith a solidly'constructed canopy posit1oned-above the heater or burner to diffuse the heat. No

provision was made-to changethe shape of the canopy'by an -adjustment of'the same in the-process of brooding the jchlcks in" order to regulate th'e-fdiflusionjofheat; 7A

damper, located generally at the top offthe canopy, was the onlym'e'ansto aid'in the fusionof heat, except possiblyatarget ordi aphragm. The damper opening was the "only this type of brooder most of the utilized heat generated by the heateror burner is directed to thefioor of the'brooder house under and just a little beyond the canopy; an indeed very limited area. In order to successfully hover a large brood of chicks it is necessary to diffuse the heat of the heater or burner over a large area, especially during the night-time. Unless the heat is well difi'used about the brooder there will be crowding of the chicks and a consequent loss in lives. 7 a i The objects of my invention arezfirst, to provide a chick brooder of this class having a canopy made of sect-ions or wings so arranged that it maybe easily opened or closed for the purpose of attaining a more favorable diffusion of heat and better ventilation in the process of brooding chicks or other domestic fowls; second, to provide a novelly constructed and operated apparatus of this class.

With these and other objects in view, as a this ap- Figure 1 is a perspective view of my in vention, showing by dash-dot lines the open position of the canopy roof sections orwings and othe r correspondingly shifted parts.

Figure 2 is a plan view of the same, showing by dotted lines certain hidden parts of deviceusedto opener close the canopy sec t ons or w ngs; v. 1

'My chick brooder i consists of preferably" an oil burner 11, a"feed' line12to supplyoilf I to the burner from thereservoir 13,11. canopy plate 15' by means of hinges 17, a' device to '70 'comprising a supporting frame made -Of' metallegsl i secured to a metal'plate 15 and open or close the sheet-metal sections or wings 16 and consisting of a wooden handle 18 secured to the reciprocating metal rod 19 which is held in a vertical position by the plate 15 and the guide 20,which is in turn secured to the "plate 515, a circular metal 22 secured to the sections or Wings 16, and a combined stop and lock 23 secured to the rod 19. By applying a downward pressure plate 21 secured to the rod 19, metal levers with the hand on the handle 18 the rod 19 and plate 21 are caused to move downward. The downward movement of the plate 21 forces the ends of the levers 22 next to said plate to move downward and at the same time causes the opposite ends of the; same said levers together: with the sections or wings 16 to rise, the sections or wings 16 swinging on the hinges 17. A combined stop and lock 23 limits the downward movement of the rod 19 and holds the brooder canopy open by engaging with guide 20. By tripping the lock 23 the canopy is closed.

Duringthe day time when the air is likely to be moving swiftly'in the brooder'house owing to the activity of the chicks and open I windows the canopy of my brooder is kept,

under the canopy. It istoo hot for chicks to sleep under the canopy but it does Well for them to run under the canopy and get,

warmed in an instant. This they repeat at pleasure. M

During the night time When the brooder house is more. or less. closed and the chicks are still there is little movement of the air. In this still atn'iosphere it isnecessary that the brooder should aid ventilation and not keep any foul gases near the floor. The heat should also he diffused over a largetfioor area so as to reach all the birds. These: objects are attained by keeping the canopy of my brooder open during the night. It is an imitation of the mother hen when she spreads her Wings'to hover her brood.

From the description given it is obvious that my brooder has distinct advantages over the old ,type of canopy brooder. In the old type brooder there is usually a damper .control in the top of the canopy. When this damper isopen itdoes not cause an eflicient distribution of the heat about the chicks. Most of the heat escapes. Whereas, in my type of canopy the heat is. more efficiently diffused about the. chicks and it'isnot allowed. to escape immediately above the burner. The plate 21 serves as a target for the flame of the burner.

It isto be understoodthat the form of my invention herein shown anddescribed is a supporting'frame, a roof made of Wings. hinged to said supportlngirame, a manual means for either opening or closing said wings and acombined stop and lock-to limit the movement of the said wings and also to hold them op n- I 2. A chickbroode'r consisting of aheater and a canopypositioned above. the heater tod iliusethe heat, said canopy comprising a.

supporting frame, a roof made of Wings hinged to said supporting-frame; said ings capable of be'ing manually openedor closed,

by levers secured to them and actuated; by means of a plate. secured. to a vertically positioned. reciprocating rod mounted on the, said supporting frame of said, canopy, and having a handle secured. to said reciprocating rod for manually operating thezsame.

In testimony whereof I affix'my signature.
